When Marlin was using chemicals on the dairy farm, he would put 100% ammonia in the sprayer and spray it out. Couldn't it be sprayed on a road?
We have hard limestone water. That will also leave a white line or film where it sets. An acid like vinegar or a Lime-A-Way product can remove that kind of deposit. Hard water can also clog sprayer nozzles.
Best Wishes,

Subject: [Market-farming] organic standards for cleaning out conventionalboom sprayer
We recently purchased a formerly conventional boom sprayer for use with possibly some biodynamic sprays and definitely compost tea and some other liquid nutrients. I would like to do a 1-time conversion to organic with the sprayer, but have no idea what the organic standards require (we're not actually certified - but I believe in the standards). I'm also concerned about a quantity of dry whitish material on the bottom of the tank - how would I safely get rid of what ever it is? The sprayer was used for round-up for weed control on berries and small fruits - I don't know if any other materials were used in it. I have no experience with conventional stuff - should I be wearing rubber gloves, respirator, etc?
Thanks much for any input!
